Definitions
- the present invention relates to a water trough for livestock which is level constant and frost-free.
- the present invention relates to such a drinker.
- the trough according to the present invention is an open trough trough, in which a water reserve is maintained at a constant level by a float valve, characterized by the fact that it consists of the superposition of a hollow support insulating, of a sealed volume filled with heated air and a volume open to the open air filled with water at a constant level and constituting the watering tank, and in that the side wall of the tank is double so as to provide a space around its entire periphery between the inner wall and the outer wall, this space communicating with the space filled with hot air so that the tank has its bottom and its sides surrounded by air hot.
- the upper wall of the support and the walls of the tank are shaped so as to define between them a volume is very enveloping, although it can be reduced, waterproof, also filled with air, in which the heating means are placed so that the trough is constituted by the stacking of three volumes: the volume filled with air from the support hollow; the volume filled with heated air located between the hollow support and the tank watering; the volume filled with water from the tank.
- the drinker according to the invention comprises a hollow support 10 on which a tank 30 is placed.
- the hollow support 10 is constituted by a lower wall 11, an upper wall 12, and a side wall 13, these walls defining a closed volume, filled with air.
- the central part 12a of the upper wall 12 is at a level lower than that of its rim 12b and has several bosses such as 12c.
- the tank 30 has a central part 31 and a peripheral rim which is constituted by folding back on itself the wall of the tank so as to define a space 32 included between two walls 33 and 34.
- the wall 34 rests on the rim 12b of the hollow support 10.
- the wall 34 is slightly larger than the wall 33 so that the bottom 31 of the tank is slightly raised relative to its edges.
- the formation of the walls of the support 10 and of the tank 30 provides a hollow volume 20 between both.
- This volume 20 communicates with the space 32 which surrounds the tank of the tank 30.
- the previously mentioned bosses 12c protrude into the volume 20 and bear hot plates 21, heated by resistors 22.
- Inside the volume 20 are also arranged the electrical connection means 23.
- the height of the bosses 12c is determined so that the heating plates 21 are not in contact with the wall 31 of the bottom of the tank 30 but at a distance of about 1 cm.
- the internal side wall 33 of the container 30 is formed so as to include a bulge 35 inside which is disposed the pipe 36 which brings the water to the valves 37 associated in known manner with a float 38.
- the support 10 and the tray 30 are rectangular; bulge 35 is arranged in the middle of the long side of the rectangle and the cover 40 extends over the entire width of the tank so as to protect the fittings 37 and the float 38 while separating the two-part water tank.
- the bottom 31 of the tank 30 being near the heating plates 21 is heated by these.
- the air in the closed volume 20 is also heated by said plates 21 and, as this volume 20 communicates with the volume 32 it follows that the watering tank of the tank 30 is entirely surrounded by air hot.
- Heating by direct radiation of the plates 21 and by air envelopment hot allows with a very low power, of 100 Watts, to maintain frost free quantity of 40 liters of water up to temperatures of the order of - 35 °.
- a seal 24 is disposed between the tank 30 and the support 10 of so that the volume 20 is sealed and that there is no leakage of hot air.
- the function of the volume of air inside the hollow support is to isolate the volume of hot air 20.
- This volume of air can advantageously be replaced by a insulation such as polyurethane foam.
- the trough thus described can be placed on the ground or on a concrete support (area straw).
- this support can be a concrete base 50.
- this base 50 has a bore 51 which is crossed by the pipe water supply 52 and the power supply cable 53.
- This chute 60 passes through a conduit 62 shaped in the walls 11 and 12 of the support 10 and a cylindrical seal 63, surrounding the chute 60 is interposed between the tank 30 and the support 10 so as to seal the volume of hot air 20.
- the conduit 62 can communicate towards the outside by a lateral conduit 66 formed in the support 10 or in a pipe 54 passing through the concrete base 50 towards a sump 55.
- the dimensions of the chute 60 and the lateral conduit 66 are such that it is possible to fit on said chute 60 a flexible pipe arriving via the conduit lateral 66 in order to avoid that, as is the case in known devices, water polluted is evacuated on the ground surrounding the trough, this water coming to wet the mulched area that surrounds the drinker and soak the soil on which the animals come to trample.
- the pipe 136 which brings the water to the tap is constituted by a tubing flexible which is arranged inside the sealed volume 20 by describing for example a circle or an arc.
- the length of this tubing can be of the order of 30 centimeters.
- the water contained in the flexible tubing has time to reheat between two fillings of tank 30.
- This heated water communicates the heat towards the tap 37 and the water supply pipe, which contributes to the frost protection of pipes and fittings.
- This arrangement is also advantageous in that it allows, when necessary intervene in the sealed volume 20, open the drinker by simply removing the fastening means 100 without having to uncouple the pipe 136 because the flexible tubing can deform and allow separation of the tank 30 and the support hollow 10.
- the device thus described therefore comprises the superimposition of a sealed insulating volume 10, which can be filled with either air or an insulating material; with a sealed volume 20 filled with hot air; and of a volume 30, open to free pair, filled with a quantity water constant.

Description
La présente invention est relative à un abreuvoir pour le bétail qui est à niveau constant et hors gel.The present invention relates to a water trough for livestock which is level constant and frost-free.
Dans la demande de brevet européen EP 0 752 206 du 3 juillet 1996, on a décrit un abreuvoir, destiné à être placé en plein air, qui comporte des moyens de chauffage qui permettent de fournir au bétail une eau tiède même par temps très froid. Un tel abreuvoir ne peut pas être à niveau constant parce que l'eau serait en permanence exposée à la température extérieure et ainsi constamment refroidie. En conséquence l'abreuvoir décrit au brevet EP 0 752 206 comporte une pluralité de bols, chacun muni d'une palette actionnée par l'animal pour remplir le bol à partir d'un réservoir central comportant de l'eau chauffée par une résistance électrique. Un tel abreuvoir est cher parce qu'il nécessite autant de robinetteries qu'il y a de bols et consomme beaucoup d'électricité, environ 3000 Watts.In European patent application EP 0 752 206 of July 3, 1996, a drinker, intended to be placed outdoors, which includes heating means which provide livestock with warm water even in very cold weather. Such drinker cannot be at constant level because the water would be constantly exposed to the outside temperature and thus constantly cooled. Consequently the drinker described in patent EP 0 752 206 comprises a plurality of bowls, each fitted with a pallet operated by the animal to fill the bowl from a tank central with water heated by an electric resistance. Such a drinker is expensive because it requires as many fittings as there are bowls and consumes lots of electricity, around 3000 Watts.
Dans la demande de brevet européen EP 0 753 250 du 12 juillet 1996 on a décrit un dispositif beaucoup moins onéreux qui est un bac isotherme, sans moyen de chauffage.In European patent application EP 0 753 250 of July 12, 1996, a much less expensive device which is an insulated container, with no means of heater.
Il s'avère cependant nécessaire d'avoir dans certains cas des abreuvoirs comportant un bac d'abreuvement assez important pour que plusieurs animaux puissent s'abreuver simultanément, qui soit à niveau constant, mais qui soit hors gel sans que cela n'entraíne une consommation d'électricité importante.It is however necessary in certain cases to have drinkers comprising a watering tank large enough for several animals to drink simultaneously, which is at a constant level, but which is frost-free without that does not involve a significant consumption of electricity.
La présente invention est relative à un tel abreuvoir.The present invention relates to such a drinker.
L'abreuvoir selon la présente invention est un abreuvoir à bac ouvert, dans lequel une réserve d'eau est maintenue à un niveau constant par une robinetterie à flotteur, caractérisé par le fait qu'il est constitué par la superposition d'un support creux isolant, d'un volume étanche rempli d'air chauffé et d'un volume ouvert à l'air libre rempli d'eau à un niveau constant et constituant le bac d'abreuvement, et en ce que la paroi latérale du bac est double de façon à ménager sur toute sa périphérie un espace entre la paroi interne et la paroi externe, cet espace communiquant avec l'espace rempli d'air chaud de telle sorte que le bac ait son fond et ses côtés entourés d'air chaud. The trough according to the present invention is an open trough trough, in which a water reserve is maintained at a constant level by a float valve, characterized by the fact that it consists of the superposition of a hollow support insulating, of a sealed volume filled with heated air and a volume open to the open air filled with water at a constant level and constituting the watering tank, and in that the side wall of the tank is double so as to provide a space around its entire periphery between the inner wall and the outer wall, this space communicating with the space filled with hot air so that the tank has its bottom and its sides surrounded by air hot.
Selon un mode préférentiel de réalisation de l'invention la paroi supérieure du support et les parois du bac sont conformées de façon à définir entre elles un volume est très enveloppant, bien que pouvant être réduit, étanche, également rempli d'air, dans lequel sont placés les moyens de chauffage de telle sorte que l'abreuvoir est constitué par l'empilement de trois volumes: le volume rempli d'air du support creux; le volume rempli d'air chauffé situé entre le support creux et le bac d'abreuvement ; le volume rempli d'eau du bac.According to a preferred embodiment of the invention, the upper wall of the support and the walls of the tank are shaped so as to define between them a volume is very enveloping, although it can be reduced, waterproof, also filled with air, in which the heating means are placed so that the trough is constituted by the stacking of three volumes: the volume filled with air from the support hollow; the volume filled with heated air located between the hollow support and the tank watering; the volume filled with water from the tank.
Grâce à cette disposition on obtient un bac d'abreuvement à niveau constant permettant de disposer à l'air libre une quantité d'eau de 40 litres, qui demeure hors gel jusqu'à une température de - 35° tout en ne consommant que 100 Watts.Thanks to this arrangement, a constant level drinking trough is obtained. allowing to have in the open air a quantity of water of 40 liters, which remains outside freezing down to a temperature of - 35 ° while consuming only 100 Watts.
A titre d'exemple non limitatif et pour faciliter la compréhension de l'invention on a
représenté aux dessins annexés :
En se reportant à ces figures on voit que l'abreuvoir selon l'invention comporte un
support creux 10 sur lequel est posé un bac 30.Referring to these figures it can be seen that the drinker according to the invention comprises a
Le support creux 10 est constitué par une paroi inférieure 11, une paroi supérieure
12, et une paroi latérale 13, ces parois définissant un volume fermé, rempli d'air. La
partie centrale 12a de la paroi supérieure 12 est à un niveau inférieur à celui de son
rebord 12b et comporte plusieurs bossages tels que 12c. The
Le bac 30 comporte une partie centrale 31 et un rebord périphérique qui est constitué
en repliant sur elle-même la paroi du bac de façon à définir un espace 32 compris
entre deux parois 33 et 34. La paroi 34 repose sur le rebord 12b du support creux 10.The
De préférence, comme cela est représenté, la paroi 34 est un peu plus grande que la
paroi 33 de sorte que le fond 31 du bac est un peu surélevé par rapport à ses bords.Preferably, as shown, the
La formation des parois du support 10 et du bac 30 ménage un volume creux 20 entre
les deux. Ce volume 20 communique avec l'espace 32 qui entoure la cuve du bac 30.
Des bossages 12c mentionnés précédemment font saillie dans le volume 20 et portent
des plaques chauffantes 21, chauffées par des résistances 22. A l'intérieur du volume
20 sont également disposés les moyens de connexion électriques 23. La hauteur des
bossages 12c est déterminée de façon que les plaques chauffantes 21 ne soient pas en
contact avec la paroi 31 du fond du bac 30 mais à une distance d'environ 1cm.The formation of the walls of the
La paroi latérale interne 33 du bac 30 est constituée de façon à comporter un
renflement 35 à l'intérieur duquel est disposée la canalisation 36 qui amène l'eau à la
robinetterie 37 associée de façon connue à un flotteur 38.The
De préférence, le support 10 et le bac 30 sont rectangulaires ; le renflement 35 est
disposé au milieu du grand côté du rectangle et le couvercle 40 s'étend sur toute la
largeur du bac de façon à protéger la robinetterie 37 et le flotteur 38 tout en séparant
la cuve d'abreuvement en deux parties.Preferably, the
Le fond 31 du bac 30 étant à proximité des plaques chauffantes 21 est chauffé par
celles-ci. De plus, l'air se trouvant dans le volume 20 qui est clos est également
chauffé par lesdites plaques 21 et, comme ce volume 20 communique avec le volume
32 il en résulte que la cuve d'abreuvement du bac 30 est entièrement entourée d'air
chaud.The
Le chauffage par rayonnement direct des plaques 21 et par l'enveloppement d'air
chaud permet avec une puissance très faible, de 100 Watts, de maintenir hors gel une
quantité de 40 litres d'eau jusqu'à des températures de l'ordre de - 35°.Heating by direct radiation of the
De préférence, un joint d'étanchéité 24 est disposé entre le bac 30 et le support 10 de
façon que le volume 20 soit étanche et qu'il n'y ait pas de fuites d'air chaud. Preferably, a
Le volume d'air se trouvant à l'intérieur du support creux a pour fonction d'isoler le
volume d'air chaud 20. Ce volume d'air peut avantageusement être remplacé par un
isolant tel que de la mousse de polyuréthanne.The function of the volume of air inside the hollow support is to isolate the
volume of
L'abreuvoir ainsi décrit peut être posé à même le sol ou sur un support bétonné (aire paillée).The trough thus described can be placed on the ground or on a concrete support (area straw).
Comme représenté à la figure 4 ce support peut être un socle en béton 50.As shown in FIG. 4, this support can be a
De préférence ce socle 50 comporte un perçage 51 qui est traversé par la canalisation
d'alimentation en eau 52 et le câble d'alimentation électrique 53.Preferably this
Le défaut usuel des bacs d'abreuvement à niveau constant est que l'eau qu'ils contiennent est très rapidement polluée par la bave des animaux et les détritus de nourriture qui sont collés à leurs babines. Il faut donc très fréquemment les vider pour les nettoyer.The common defect of constant level water troughs is that the water they contain is very quickly polluted by animal drool and litter from food that is stuck to their lips. They must therefore be emptied very frequently to clean them.
Afin de permettre la vidange de l'eau se trouvant dans le bas 30, on a disposé dans le
fond 31 dudit bac 30 une goulotte d'évacuation 60 munie d'un bouchon 61.In order to allow the drainage of the water located in the
Cette goulotte 60 traverse un conduit 62 conformé dans les parois 11 et 12 du support
10 et un joint d'étanchéité cylindrique 63, entourant la goulotte 60 est interposé entre
le bac 30 et le support 10 de façon à assurer l'étanchéité du volume d'air chaud 20.This
Le conduit 62 peut communiquer vers l'extérieur par un conduit latéral 66 ménagé
dans le support 10 ou dans une conduite 54 traversant le socle en béton 50 vers un
puisard 55.The
Les dimensions de la goulotte 60 et du conduit latéral 66 sont telles qu'il est possible
d'emmancher sur ladite goulotte 60 une canalisation souple arrivant par le conduit
latéral 66 afin d'éviter que, comme c'est le cas dans les dispositifs connus, l'eau
polluée soit évacuée à même le sol environnant l'abreuvoir, cette eau venant mouiller
l'aire paillée qui entoure l'abreuvoir et détremper le sol sur lequel les animaux
viennent piétiner.The dimensions of the
Suivant un mode de réalisation préféré, et comme représenté aux figures 5 et 6, la
canalisation 136 qui amène l'eau à la robinetterie est constituée par une tubulure
flexible qui est disposée à l'intérieur du volume étanche 20 en décrivant par exemple
un cercle ou un arc de cercle. La longueur de cette tubulure peut être de l'ordre de 30
centimètres.According to a preferred embodiment, and as shown in Figures 5 and 6, the
Par cette disposition, l'eau contenue dans la tubulure flexible a le temps de se
réchauffer entre deux remplissages du bac 30. Cette eau réchauffée communique de
la chaleur en direction de la robinetterie 37 et de la canalisation d'amenée d'eau ce
qui contribue à la mise hors gel de la canalisation et de la robinetterie.By this arrangement, the water contained in the flexible tubing has time to
reheat between two fillings of
Cette disposition est également avantageuse en ce qu'elle permet, lorsqu'il faut
intervenir dans le volume étanche 20, d'ouvrir l'abreuvoir en enlevant simplement les
moyens de fixation 100 sans avoir à désaccoupler la canalisation 136 du fait que la
tubulure flexible peut se déformer et permettre la séparation du bac 30 et du support
creux 10.This arrangement is also advantageous in that it allows, when necessary
intervene in the sealed
Le dispositif ainsi décrit comporte donc la superposition d'un volume étanche isolant
10, qui peut être rempli soit d'air, soit d'une matière isolante ; d'un volume étanche 20
rempli d'air chaud ; et d'un volume 30, ouvert à Pair libre, rempli d'une quantité
constante d'eau.The device thus described therefore comprises the superimposition of a sealed
